There is a Consensus in place concerning the following issues
related to the Qur'an:

1. The veracity of all that is contained in the Qur'an.
(SIHHAT KULLI MA FI AL-QUR'AN)

Anyone who denies one single ruling or account stated in the Qur'an,
or who denies something the Qur'an establishes as true, or who
establishes as true something which the Qur'an denies, or professes
doubt in any of the above: he is an apostate and disbeliever by Consensus.

There is Consensus on the fact that the order of the verses in
each of the suras of Qur'an and their successive arrangement
in the present order in the mushaf is so decreed by Allah,
and on that basis has the Community related it from the
Prophet, blessings and peace upon him.

Anyone who adds one letter to the Qur'an other than the narrated
recitations which are universally preserved and transmitted,
or who subtracts from the Qur'an one letter, or exchanges one
of its letters with another; and to whom has been shown the
proof that the letter he added or the change he has effected is
not of the Qur'an, or that the letter he subtracted is of the
Qur'an; and yet he continues deliberately in doing any of the
above, in full knowledge that it is contrary to what is done by
the Muslims: such a person is an apostate and disbeliever by
Consensus.

There is consensus that the explanation of the Qur'an by the
ulama is excellent, and that it is forbidden that the unqualified
explain, translate, or speak about its meanings.

8. Touching the Qur'an only in a state of ablution.
(AL-WUDU' LI MASS AL-MUSHAF)

It is forbidden for one in a state of minor impurity (al-muhdith)
to touch or carry the mushaf. These are the words of `Ali, Sa`d
ibn Abi Waqqas, and Ibn `Umar. None of the Companions is known to
have contradicted them on this. There is Consensus that it is
not permissible for the muhdath to touch it even with other than
the limbs of ablution (wudu'), such as the chest.
